SRC Members want to kill white people with AK47

When a member of any community threatens to kill white people or any other race group based on their ethnicity ( that includes me or my family ) with an AK47, and he states that he been thinking about it for a while, I believe the threat is real and would like the SAPS to arrest this individual and charge him. Using a public platform like facebook to advertise your agenda of hate and violence has been deemed illegal. Several people has already been charged for using facebook to be racist, I expect the government to act the same against this individual.
